The present study aims to investigate the impact of income inequality and economic growth on carbon dioxide (CO2) emission through moderating role innovation in China at national regional levels. To test hypothesised relationships, this took data from 1995 2015 employed panel estimation. Findings whole analysis show that influence CO2 China. Moreover, technological moderates proposed link. However, findings level are mixed, thus confirming existence differences. Policy implications also discussed.
Abstract Anion exchange is an effective strategy to regulate the composition and optoelectronic properties of perovskite quantum dots (PQDs). Though promising, it more desirable synthesize PQDs avoid decrease photoluminescence yield (PLQY). Herein, we developed a ligand mediated anion approach, in which phase transition from CsPbBr 3 QDs CsPbI was observed with introduction N‐Acetyl‐ l ‐cysteine (NAC) 1,3‐dimethylimidazolium iodide (DMII) aqueous solution solution. NAC expected create...
The compatibility of low infrared emission and wideband microwave absorption has drawn extensive attention, both theoretically practically. In this paper, an infrared-radar-compatible stealth metasurface is designed using transparent conductive materials, namely indium tin oxide (ITO) poly methacrylimide (PMI). structure a combination radar-absorbing layer (RAL) low-infrared-emission (IRSL), with overall thickness about 1.7 mm. It consists three layers, top-layer patch-type ITO...
Abstract Background To date, the relationship between thyroid dysfunction and subcortical ischemic vascular disease ( SIVD )‐induced cognitive impairments still remains elusive. Methods Cognitive performances were examined in 215 participants, including 54 healthy 52 patients with no dementia SIVDND ), 55 mild impairment SVMCI VD ). Serum thyroid‐stimulating hormone TSH total triiodothyronine TT 3), free FT thyroxine 4) 4), thyroglobulin antibody TGA antithyroid peroxidase TPO ‐Abs)...
The characteristic matrix method in thin-film optical theory was used to calculate heterogeneous doped one-dimensional photonic crystals (1-D PCs), which were fabricated by alternate deposition of Te, ZnSe, and Si materials on a silicon wafer. structure adopted broaden the band gap, within low reflection valley achieved doping. Infrared spectrum tests showed that average emissivities 1-D PC 0.0845 0.281, corresponding, respectively, bands 3 5 8 14 μm. Moreover, emissivity 0.45 over μm...
Abstract Manipulation of electromagnetic (EM) waves is essential for various microwave applications. This research studies the modulation EM by using single-layer plasma arrays consisting discharge tubes. We experimentally investigate transmission spectra and backscattering attenuation characteristics arrays, numerical simulations further reveal mechanism influences arrays. The experimental results show that broadband tunable photonic bandgaps can be achieved in frequency ranges 4–7.5 GHz...

It found that...
Carbon-based carbides have attracted tremendous attention for electromagnetic energy attenuation due to their adjustable dielectric properties, oxidation resistance, and good chemical stability. Herein, we reasonably regulate the growth of dopamine hydrochloride on surface Mo-glycerate (Mo-GL) microsphere then transform resultant Mo-polydopamine (Mo-PD) into a dual-shell Mo2C/C (DS-Mo2C/C) in high-temperature pyrolysis process under an inert atmosphere. It is found that temperature plays...
The distribution of the electron density along a plasma antenna can influence antenna’s performance. But little has been done in this regard former studies. In paper, model practical with an inhomogeneous is founded according to transmission-line equivalent theory metal monopole, from which current and radiation pattern appropriate parameters are calculated. results show that electrical distribution, maximum direction, beamwidth vary distributions. To validate model, same also simulated...
Multiple scattering of ultrahigh frequency (UHF) electromagnetic waves by two argon plasma cylinders is investigated, rigorously applying the boundary value method.
